Brett Wedewer and his wife were asleep in their million-dollar Sammamish house Friday night at about midnight when they heard what sounded like a bomb going off.

“We jumped up and ran to the window to see what the hell happened,” Wedewer said.

The back of a white pickup was sticking out of his dream house — the one he and his wife had custom-built and moved into two days after Christmas. The couple pictured their 18-month-old son learning to ride a bike on the sidewalk there.

By the time Wedewer got his pants on, he heard tires squealing. When he got downstairs, the truck was speeding away, and the smell of natural gas was filling the air.

Wedewer realized the truck had hit the house’s main gas line.

He and his wife, Staci Martin, scooped up their toddler and evacuated the neighbors.

“We thought the whole place was going to blow up.”

Fortunately, when firefighters arrived, they were able to shut off the gas.

Now the family is staying with Martin’s parents in Kirkland while they wait to see what will come of their home, and how much of it they will have to rebuild.

The pickup that smashed into the house left a trail of insulation dust from the home for about a mile, police told Wedewer.

Wedewer found the truck’s grille in the rubble of his office — a Ford Super Duty is out there somewhere without a grille, but police said the driver could be anywhere by now.

The house has a hole in it that Wedewer estimates is 15 feet by 10 feet.

Wedewer’s home office was destroyed. Just an hour earlier, he was working on his computer in that room.

“Had I stayed there,” he said, “I would have been killed.”
